∇

Properties

  • based on the inlet-outlet condition
  • sets the turbulent kinetic energy based on the patch velocity and user-supplied turbulence intensity
\[k_p = 1.5 \left( I \mag{\u} \right)^2\]
  • in the event of reverse flow, a zeroGradient condition is applied, i.e.
\[\frac{d k}{d x} = 0\]

Usage

The condition is specified in the field file using:

<patchName>
{
    type        turbulentIntensityKineticEnergyInlet;
    intensity   0.05;
    value       <field value>;

    // Optional entries
    U           U;
    phi         phi;
}
